VALVE PROTECTOR AND FASTENER FOR PNEUIVIATIC TIRES.

SPECIFICATION forming part of Letters Patent No. 656,054, dated August14, 1900. Applicata nea April 10,1900. sehn No. 12,307. da model.)

To all whom z5 may concern:

Be it known that LWILLIAM E. SMITH, a citizen of the United States,residing at Johnstown, in the county of Cambria and State ofPennsylvania, have invented a certain new and useful Valve Protector andFastener for Pneumatic Tires, oflwhich the following isa specification,reference being had therein to the accompanying drawings.`

This invention relates to valve protectors and fasteners for pneumatictires, the object in'view being to provide mechanical fastening means,used with or without the usual cement, for holding the tire in the rim.

The fasteners are especially designed to hold the tire againstlongitudinal movement on the rim, or, in other words, to prevent what isknown as creeping, the result of which, as is well understood, is togradually chafe, weaken, Yand finally break off the valvetube, whichprojects inward from the tire and 'passes through the usualvalve-opening in the rim. l

The detailed objects and advantages of the invention will more fullyappear in the cou rse of the ensuing description.

The invention consists in a valve protector and fastener for pneumatictires embodying certain novel features and details of construction andarrangement of parts, as hereinafter fully described, illustrated in thedrawings, and incorporated in the claim.

In the accompanying drawings, Figure lis a longitudinal sectional viewof a tire and rim, showing two fasteners applied thereto. Fig. 2 is across-sectional view of the tire and rim, showing one of the fasteners.Fig. 3 is a detail perspective view of one of the fas-V teners. Fig. 4is a bottom plan view of one of the fasteners.

Similar numerals of reference are employed:-

lThe tire may be either of the are arranged at opposite sides of thevalve and at points equidistant therefrom, as shown in Fig. l, and alsomidway between adjacent spokes, as shown in the same ligure. Eachfastener comprises a head 6, in the form of a sheet-metal plate, and apin 7 connected at one end to the center of the head or plate 6 andadapted to be received in an opening 8in the rim 1, as shown at Figs. 1and 2. The head Gis curved longitudinally, as shown in Figs. 1 and 3, toconform to the circumference or curvature of the tire and rim, and it isalso curved or dished transversely, as shown in/ Figs. 2 and 3, toconform t0 the cross-sectional curvature of the tire and tirereceivingsurface of the rim. The head 6 is further punched at several points toform outwardly-proj ectin g integral barbs 9, which become embedded inthe rubber tire, an'd thereby obtain a firm hold thereon. The head 6 isalso provided with a series of openings 10, which servea twofoldpurpose-first, to skeletonize and reduce the weight of the head 6, and,secondly, to allow the material of which the tire is composed to enterand ll the openings, thus securely anchoring the head or plate 6 in thebody of the rubber at the rim-engaging portion thereof, as shown in Fig.2.

It will be understood from the foregoing and by reference to Figs. 1 and2 that the head, or plate 6 is embedded and concealed and entirelyinclosed within the material of the tire, the tire in the process ofmanufacture being molded around said head or plate and passing throughthe openings 10, and also forming around the barbs 9. By locating afastener at each side of the valve tube 0r stem the tire is preventedfroln creeping as to Y that portion which lies adjacent to thevalve-tube, thus preventing the valve tube or stern from becoming wornat its junction with the tire and finally breaking off or tearing, so asto leak and permit the air within the tire to escape. The openings S inthe rim may pass only partially or entirely therethrough, as may bepreferred.

I-Iaving thus describedthe invention, what is claimed as new is- Thecombination with a wheel-rim, and a pneumatic tire having a valve-tubepassing through an opening in the rim, of a pair of fasroo tenerslocated on opposite sides ofthe Valvetube and each comprising a piuremovably tted in an opening in the rim, and a head in the form of asheet-metal plate to 4which the pin is secured, said head being providedWtha plurality of openings for the reception of the tire material andfurther punched to form a series of barbs which are embedded in the tirematerial, the head beinginolosed and Concealed wil-hin the rim portionof the tire, io
